Molar Mass of Li3N: Quick Calculation Guide

Understanding the molar mass of Li3N is crucial for students and professionals in chemistry, materials science, and related fields. Lithium nitride (Li3N) is a compound with significant applications in batteries and solid-state physics. This guide provides a quick calculation method to determine its molar mass, ensuring accuracy and clarity.

What is the Molar Mass of Li3N?

The molar mass of a compound is the sum of the atomic masses of all atoms in its chemical formula. For Li3N, it consists of three lithium (Li) atoms and one nitrogen (N) atom.

Step 1: Identify Atomic Masses

• Lithium (Li): Atomic mass ≈ 6.94 g/mol
  
• Nitrogen (N): Atomic mass ≈ 14.01 g/mol
  

Step 2: Calculate Molar Mass of Li3N

1. Multiply the atomic mass of lithium by 3:
   3 × 6.94 = 20.82 g/mol
   
2. Add the atomic mass of nitrogen:
   20.82 + 14.01 = 34.83 g/mol
   

📌 Note: Ensure you use accurate atomic masses from the periodic table for precise calculations.

Why is the Molar Mass of Li3N Important?

Knowing the molar mass of Li3N is essential for:
- Stoichiometry calculations in chemical reactions.
